The magazine contained articles on professional game development topics relating to game programming, art, audio, quality control, design, and production. Monthly columns from industry veterans offered in depth discussion on a variety of topics. It had articles by notable game industry figures and reviews on game development related books, tools, and software packages. The back page "Soapbox" was also a popular feature but moved to sister site to Gamasutra circa 2004. It was replaced by a splash art page called "Thousand Words" and then replaced again with a regular column "Arrested Development."
Game Developer's most popular feature was probably its monthly "Postmortem" column which discusses the recent development of a video game with the top five each of "What Went Right" and "What Went Wrong". It provided a frank, first-hand account of the lessons learned in the development process. The first Postmortem was featured in October 1997 and written by Andre Vrignaud on Dark Sun Online. Starting in 1998, Game Developer recognized exceptional game development tools with their "Front Line Awards," which were given annually. Winners included software (such as Photoshop and VTune), game engines (Unreal engine), hardware (GeForce 3), and books (Computer Graphics: Principles and Practice).
Gamasutra, the sister publication web site of Game Developer, acts as an online resource for game developers, as well as a job posting board for employment in the game development field. It was not part of the closure that resulted in Game Developer's ending and continued some features from the magazine.
